Improvement in harvesting-machines



UNITED STATES MILTON A. WHEATON, O F SUISUN CITY, CALIFORNIA.

IMPROVEMENT IN HARVESTING-MACHINES.

Specification forming part of Letters Patent No.49,l.86,' dated August 1, 1865.

To all whom fit may concern Be it known that I, MIL'roN A. WHEAToN, ot Suisnn City, Solano county, State ot'Galifornia, have invented certain new and useful Improvement in Iteaping, Mowing, and Heading Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had .to the accompanying drawings, making a part of this specication, in which- Figure l is a plan or top view of a harvester having Iny improvements. Fig. 2 isa side view ofthe same.

Similar letters of reference indicate like parts in the two figures.

Thisinvention consists in an improved means for throwing the sickle ofthe reapcr or mower out of gear.

It also relates to the employment or use of oscillating bars suspended above the machine for the purpose ot' holding the friction-rollers in place.

The object of my invention is to avoid the friction of guides or sliding surfaces of any kind.

To enable others skilled in the art to make and use my invention. I will proceed to de scribe it.

In the accompanying drawings, Figs. l and 2, A represents the driving-wheel, in which is placed the camrim B, and upon which the friction-rollers D D revolve, and are held irml y against the cam-teeth by means of the vibrating lever C, and to which the collar H is attached, encircling the driving-shaft. I place another collar, Hf, upon the shaft, to which is attached a lever, I, which is moved by the connecting-rod J and lever K. Each collar contains one or more depressions and projections on itsface, and when the lever is moved backward the depressions on one collar correspond with4 the projections on the other, so that the vibratingbar C, together with the friction-rollers D D', can be thrown away from the cam-rim B,

by jointed connections from `the bars F F', j

which are elevated above the frame for the purpose of avoiding the friction of guides and sliding surfaces, and at the same time to allow the friction-rollers Dv D to be Inoved easily to and from the teeth of the cam-rim `B and pre-n vent them from being moved up and down.

The collar H, to which is attached the lever I,.is kept in place by means of a pin passing through the driving shaft, or by another stationary collar.

These improvements are intended for use upon every kind ot' harvester to which they can be applied, whether the saine he reapers,

headers, or mowers.

Having thus described my improvement in harvesters so as to enable any one skilled in the art to make and use them, I will now state what claim and desire to secure by Letters Patent:

l. In combination with the cam-teeth B, the employment or use ot' the friction-rollers D D' and the jointed vibrating rods E E', or their equivalents, for the forth.

2. 'Bhe employment or use of the collars H H, or their equivalent, with the depressions and projections, substantially asand for the purpose specified. f i

In witness whereof I have hereunto set my hand and seal this 29th day of April, A. D.

When the lever I is purpose specified and set
